I This invention relates to the construction of concrete buildings,particularly to thecon- 'struction of the type of buildings wherein thefloors of concrete slab construction are carried on a reinforcedconcrete frame which is enclosed within a monolithic concrete wall. Sucha type of construction is sometimes employed in cold storage buildingsand the like, wherein it is desired to insulate the enclosing wallagainst transmission of heat.

The invention has to do with method and means for the construction ofthe enclosing wall, or curtain wall as it is sometimes called,

with the use of slip forms; As will be under-,

stood, slip forms are of a type in which the form panels, whichconstitute the mold s11.- faces between which the concrete is poured andshaped in the building up of thewall, are

arranged so as to be elevated from time to timein the proper position tocontinue the mold cavity on upwardly from portions of the wall alreadypoured and set, to receive additional'pourings of concrete. v

A general object of the invention'is the provision of improved methodandmeans for the construction ofcurtain walls in the dc siredassociation with frame and floor construction which is already in place.

A. more particular object is the provision of such method and meanswhereby the our tain wall may be constructed accurately and rapidly bythe employment of slip forms, withoutinvo-lving complications in themanipulation or construction of suchforms.

Still another object isthe provision of such method and means wherebythe curtain wall.

may be constructed with suitable provisions for installation ofinsulating material.

Other and further objects will be pointed out or indicated hereinafter,or.will be apparent to one skilled in the art uponan understanding ofthe invention or its employment in practice. I g

In the accompanying drawing forming apart of this specification weillustrate apparatus and construction wherein the invention maybeembodied and by which it may be practiced, but itis to be understoodthat these are presented for purposes of example only, as the inventionis not limited in embodiment COMPANY, OF CHICAGO, ILLINOIS, A

or use to the particular forms of apparatus herein shown and described.

in said drawings 1 Figzl represents anelevational view of a portion of abuilding frame with form guides in place; r

Fig.2 represents a transverse elevational view of an embodiment of ourimproved slip form in association with a portion of the buildingconstruction, and p Fig. 3 is horizontal sectional detail taken onsubstantially line 33 of Fig. 2. i

In the construction of buildings with mono-' lithic concrete walls,.itis frequently desirable to erect the frame and place the floors beforebuilding theenclosing walls; Such a has presented a 'ditficultproblem,involving various considerations not encounteredin the erection of suchWalls in advance of theplacing of the associated'floors. The presentinvention provides a solution of this problem in such fashion that thecustomary advantapges of operation with slip forms are availed Oapparatus employed,re sort will be had to the example illustrated in theaccompanying drawing. We will assume-a situation in which the buildingframe portions consisting V of the colums C and the floor portions Fineluding the beams and slabs, have been erected to a suitable height,and it is desired to close this frame portion with a curtainwallwhich-is'to be heat insulated. In the forming of the floorslabs,holes 10 are pro, vided in the slabs at suitable intervalsalons I I btheir outer margins, same being formed, for

example, by the insertion of short sections of.

Fora description of the method and the pipe in the slab forms before thefloors are poured. As a preliminary to the erection of the wall,vertically running form guides 11 are arranged at the desired horizontalintervals between the floors and atthe outer margins thereof, saidguides being lined up vertically from floor to floor. Each of. these.

' guides tightly against the slabs or beams.

The slip forms comprise a plurality of frames made up of the verticalmembers 16 which are rigidly connected in parallel. relation ship andcarry the form panels 17, the handling platform or-runway l8 andthejack' screws 19. The form panels 1? are spaced apart transversely, toaiiord the mold cavity in which the concrete is poured to form'the wallVI. The jack screws are adapted for cooperation with clamps 20 which maybe affixed to the jack rods 21 that extend vertically in the wall andconstitute the supports on which the frames and their carrying portionsmay be elevated from time to time by operation of the jack screws. Theframes are adapted to have lateral support and guidmice on the guidemembers 11, such as to maintain the forms in the desired verticalposition against't-he'weight of the handling platform. Wear strips 22are carried by the frames for bearing cooperation with the guides.desired alignment with the guides and to support them above their pointsof support on the jack rods,'the frames are provided with movable guideyokes which include the jaws 24 which are pivotally connected to theframes at 24 and are adapted wheuin their extended position to straddlethe guide struts li r The guide yokes are maintained in cooperation-withthe guide struts by bolts 24* which are removable and which carryrollers 24 adapted to ride on the inner side of the guide strut.

The slip forms being thus associated with the guides and the form panelsbeing thus nuintained in the desired position, concrete is poured in themold cavity and suitably disbuted and allowed to set to the desirednrmness. Thereupon tl e forms are elevated to the desired extent bymanipulation of the ack screws, to extend the mold cavity on upwardlyfrom the portion of the wall which has been poured. Operation continuesin this fashion, so that the wall is gradually built up by addition ofnew pourings'of concreteat the top; As one of the guideyokes is broughtto a position near the upper end of its cooperative guide 11,the bolt24% is withdrawn, and the guide jawsswung back In order to hold theframes in the to a position where they clear the margin of the floor, asillustrated by the next to the uppermost guide jaws 24: in Fig. 2. Uponfurther elevation of the form to a position where this guide yoke may beengaged with the next guide strut, the Jaws are swung out again and thebolt and roller replaced, as illustrated by the topmost guide yoke inFim 2. Thus the upward'progress of the forms'is continued throughout thedesired height of the building, the forms at all times being affordedthe proper support and guidance to insure the wall being built up in thedesired .plumbpositionandin the desired relationshi to the frame andfloors. The space S afforded between the inner surface of the wall Wandthe margin of the floor is left for the reception of insulatingmaterial, such'as slab cork, or'other desired inner surfacing for thewall. Guides 11 which have been passed by the forms, may be removed andreinstalled above the forms.- The holes 10 may be either closed by groutor may be utilized for the placement of tying connections between thewall and the floors.

By employment of the method and means I above described, thev curtainwall may be erected rapidly and accurately with employment of slip formsoperatedjin the customary;

fashion. 'The guides I 11, being made in standard lengths, maybeemployed repeatedly-on different'jobs. Q 7
